I have volume 4 of "Kuro Majyo-san ga Tooru!!" and volumes 1-18 of "Waka Okami wa Shougakusei!", plus another volume 18. Individual sales are possible, but the price will be slightly higher due to the handling fee. The condition is relatively good, but the covers of volumes 1 and 2 of "Waka Okami wa Shougakusei!" are a little dirty. I'm considering a price between 300 and 500 yen per book, depending on the condition.
